CHECK ECM (3UR-FE)
Tech Tips
As the ECM connector is a waterproof connector, it is not possible to check the voltage of each terminal or check the waveform with an oscilloscope while the ECM is installed in the vehicle.
-
Disconnect the A38 and C45 ECM connectors.
-
Measure the voltage and resistance according to the value(s) in the table below.
